Colors of electronically displayed images differ from those of printed images because active and passive light sources have different operating principles. Electronic devices use RGB color space while printing devices use CMYK color space. These differ in both color range and conversion algorithm, resulting in slightly different color effects. A printed image will appear closest to how it looks on an electronic device when the screen's backlight is set to the lowest level, and the brighter the screen backlight is, the greater the difference.

If a photo comes out blank, it may be because the photo paper was inserted upside down, which will prevent the printer from printing properly. When adding paper, make sure it is glossy side up.

The Mi Portable Photo Printer supports borderless printing. To ensure the final photo doesn't have a white border, about 1 mm around the image's edge may be cropped when printing.

Please refer to the following troubleshooting steps: 1. Make sure the output tray is not blocked. 2. Make sure the printer has enough battery. 3. Check whether the printer has encountered an error: If it has, queued print tasks will be paused until the error is cleared. Common troubleshooting solutions are provided on the app's error page.

Each pack of photo paper contains an blue calibration card to ensure the paper is aligned properly when printing. To ensure print quality, always calibrate the printer using the included calibration card after adding new photo paper.

Photo paper should be kept in a cool, dust-free, low-humidity environment out of direct sunlight. 1. High temperatures and direct sunlight can cause the paper to become discolored. 2. Humidity, water, and other liquids can cause the paper to become discolored and wrinkled. 3. Dust can cause scratches on the paper and damage the printer.

Photo paper should be adhered to a smooth, flat surface. Avoid exposing the paper to high heat and humidity, as this can cause the paper to curl up or lose its adhesive properties.

The printer has a built-in lithium battery and should not be stored in a hot or humid environment. Do not use the printer if it has been submerged in water. The printer should be recharged at least once every 3 months.
